Online IP Enforcement in Vietnam: Utilizing Site and Keyword Blocking

Subscribe to Updates
Managing Intellectual Property

The growth of Vietnam’s vibrant digital economy offers tremendous potential but is also a driver of the persistent problem of online intellectual property (IP) infringement. The spectrum of issues faced by IP rights holders runs from copyright piracy on digital services (such as streaming and torrent sites) to the sale of counterfeit goods via e-commerce sites and social platforms to the misuse of rights through misleading use of trademarks. These infringements do not only eat into profits; they damage brand reputation and mislead consumers. As a result, site blocking and keyword blocking have become increasingly important components of the enforcement toolkit available in Vietnam.

Legal Framework for Blocking Actions

Site and keyword blocking in Vietnam is supported by a growing legal framework, particularly following the 2022 amendment to the IP Law. Prior to this, the legal basis for blocking was scattered across various laws, and internet service providers (ISPs) were only obligated to block access to infringing content upon official requests from authorities.

The introduction of Article 198b under the amended IP Law marked a significant shift, establishing a clearer mechanism for rights holders to request site blocking directly. This provision obliges them to act upon valid takedown or blocking requests.

In addition to the IP Law, other key legislation includes the Law on Information Technology, the Law on Cybersecurity, the Law on Advertising, and various decrees. Together, these laws provide a more structured and enforceable basis for blocking actions in Vietnam, though practical enforcement still depends on ISP cooperation and the clarity of the infringement evidence.

Competent Authorities

Previously, rights holders could pursue administrative actions through specialized inspectorates under the Ministry of Science and Technology, the Ministry of Culture, Sports and Tourism, or the Vietnam E-Commerce and Digital Economy Agency (iDEA). However, due to a recent government restructuring, these bodies have been dissolved with their functions transitioning to the Government Inspectorate – potentially impacting enforcement timelines in the near term. Civil disputes, including blocking orders, are handled by the People’s Courts, while criminal cases are referred to the police.

Understanding the Blocking Mechanisms in Practice

To effectively deploy these measures, rights holders need to grasp their practical application. Site blocking acts as a direct blockade, intending to stop internet users residing in Vietnam from accessing certain websites deemed to host infringing content. ISPs are the main operators of these blocks, typically upon receiving a valid request or order. They employ technical methods such as DNS blocking (preventing the website’s name from resolving to an IP address), direct IP address blocking, or filtering specific URLs known to contain infringing content. The goal is plainly to deny entry to the origin of the breach from within the borders.

Keyword blocking targets the discoverability of infringing content or products. The logic is that even if an infringing site exists, making it difficult for users to locate it can help to significantly reduce its impact. This includes taking proactive measures such as requesting search engines like Google, Bing, or local alternative Cốc Cốc to remove or lower the ranking of links leading to infringing materials from search results associated with relevant keywords. It also involves working with online ad platforms such as Google Ads, YouTube, Facebook, and TikTok to prevent advertisements for counterfeit or pirated items from being displayed when users search for, or are targeted by, those specific terms. This approach effectively helps to disrupt the connection between consumer searches and infringing online offers.

Practical Steps

Implementing blocking measures requires a structured, practical approach. The process typically begins with identifying and documenting the infringement. Building and preserving strong evidence—such as conducting a bailiff recordal and, where appropriate, making test purchases—is essential to support any subsequent enforcement actions.

With solid evidence in hand, rights holders must choose the most suitable enforcement channel. This decision depends on many factors, such as the severity of the infringement, the urgency of action, and available resources. One option is to submit takedown notices directly to ISPs, using their internal reporting mechanisms. This approach can yield quick results for clear-cut violations. However, its effectiveness largely depends on the ISP’s cooperation, which can be inconsistent. ISPs may decline to act if the infringement appears debatable or too complex to assess without formal adjudication. In such cases, ISPs typically advise parties to seek resolution through appropriate authorities.

Alternatively, rights holders may file administrative complaints with the relevant authorities. This is often more efficient and cost-effective than litigation, though delays may occur due to the ongoing restructuring of the inspectorates. For e-commerce infringements, complaints can be submitted to iDEA.

Civil litigation is suitable for cases involving significant damages or injunctive relief while criminal action is necessary for serious offenses such as large-scale counterfeiting. However, both routes are time- and resource-intensive, and best reserved for major infringements.

Regardless of the enforcement route, the process typically involves the following:

  • Dossier preparation: Compiling proof of IP ownership, evidence of infringement, and legal authorizations (e.g., power of attorney). Documentation requirements may vary by ISP or authority.
  • Submission: Filing the completed dossier with the appropriate entity.
  • Review and action: ISPs may act quickly if the claim is clear, while the authorities are conducting formal reviews. If infringement is confirmed, they may impose sanctions or order content removal.

Even after enforcement, ongoing market monitoring is essential due to the high risk of repeat violations.

Final Thoughts

While site blocking and keyword blocking are not without challenges—with infringers frequently using tactics such as VPNs, domain hopping, keyword manipulation, and anonymity to evade enforcement—they remain indispensable tools for protecting IP rights in Vietnam’s increasingly digital marketplace. They provide concrete mechanisms to limit access to, and visibility of, infringing content. Site and keyword blocking should be viewed as vital components of a broader enforcement strategy—complemented by platform engagement, administrative actions, and litigation when necessary. Success requires persistence, adaptability, and a proactive approach as infringers’ tactics continue to evolve.

It is generally understood that patents are granted for new designs that have not been widely known or used in Thailand and not been disclosed anywhere prior to the date of the patent application. It is trite law that design law protects the distinctive appearance or products. Under Section 3 of the Thai Patent Act B.E. 2522, as amended by the Patent Act (No. 2) B.E. 2535 and the Patent Act (No. 3) B.E. 2542, a design is defined as “any form or composition of lines or colors that gives a product a special appearance and can serve as a pattern for an industrial or handicraft product.” This raises an important question. Can a patent be issued for a product design that contains text, numerals, trademarks, or symbols that do not fall under the definition of a design? This issue commonly arises when attempting to register packaging, labels, and graphical user interfaces (GUIs). Until a few years ago, applicants could file design applications with the Thai Patent Office for designs that contained such elements, provided that an appropriate disclaimer was included. This practice was generally accepted by Thai design examiners at that time, but the Patent Office has since implemented a change in its practice that could have a significant impact on applicants for design patents. Where design representations are submitted as line drawings or computer-aided design (CAD) drawings, the examiner may now issue an office action requiring their removal. This practice, however, appears to be applied inconsistently, as some examiners still exercise their own discretion in determining whether drawings containing these elements are acceptable. Below are examples of a GUI design, a CAD drawing design, and a photographic design representation that illustrates issues relating to the presence of nonallowable elements.

Franchising in Thailand has matured into a sizeable commercial sector, but the rules governing franchisor–franchisee relationships remain scattered across general legislation rather than consolidated in a dedicated franchise statute. In this environment, the decisions of the Trade Competition Commission of Thailand (TCCT) have emerged as valuable practical guidance. Thailand follows a civil-law system in which judicial and administrative decisions do not create binding precedent; however, past rulings are nonetheless influential. This article examines the most instructive recent TCCT decisions and distills the practical compliance considerations for franchisors and franchisees operating in Thailand. Postcontract Changes: Justified or Unfair? A recurring issue is whether a franchisor may alter the terms of engagement after contract execution. The TCCT has established that midterm modifications are not inherently unfair; the determinative factors are whether there was a reasonable business justification, adequate advance notice, and a transparent process. In a 2023 coffee franchise matter, for instance, the TCCT declined to find a violation where a franchisor increased raw material prices, noting the increase had been communicated in advance and supported by demonstrable cost pressures. A bubble tea franchise matter reinforces this principle. The TCCT found that postcontract mandatory purchases of branded syrup and flavorings were justified, as the agreement reserved the franchisor’s right to modify product requirements, the materials were sold at or below market prices, and the branded ingredients possessed distinctive qualities deemed essential to franchise quality. The complaint was dismissed, with the additional requirements characterized as a legitimate measure to preserve brand consistency. Considered together, these decisions indicate that post‑contract modifications will be evaluated against three criteria: (1) whether there is a legitimate business rationale, (2) whether adequate advance notice was provided, and (3) whether franchisees were treated equitably throughout the transition.

Significant economic challenges facing Thailand in recent years have placed financial pressure on both individuals and businesses. As a result, many debtors may find themselves unable to meet their repayment obligations, leading to bankruptcy proceedings. When an individual or corporate debtor in Thailand is subject to bankruptcy proceedings, the Thai Bankruptcy Act B.E. 2483 (1940) provides a legal framework for collecting a debtor’s assets and using them to repay creditors. Under the Bankruptcy Act, creditors wishing to recover outstanding debts must file a debt repayment application (DRA), which is the primary mechanism for asserting claims in bankruptcy proceedings. However, the filing of a DRA is subject to specific legal requirements, procedural rules, deadlines, and supporting documentation. Failure to comply with these requirements may adversely affect a creditor’s ability to recover its claim. This article highlights the key considerations that creditors should be aware of when filing a DRA in a bankruptcy case in Thailand. Filing a DRA In a bankruptcy case, after the court issues an absolute receivership order, the debtor loses the authority to manage or dispose of its assets. Control over the debtor’s assets is transferred to the official receiver, a government official responsible for administering the bankruptcy estate in accordance with the Bankruptcy Act. Creditors seeking repayment of their debts must file a DRA with the official receiver within two months of the absolute receivership order being officially published in the Government Gazette. For creditors outside of Thailand, the official receiver may extend the filing period by up to an additional two months. These filing deadlines are strictly enforced. Failure to file within the prescribed period may result in the claim being barred, except in limited circumstances permitted by the Bankruptcy Act. Where a late filing is accepted due to force majeure, the creditor may only

Vietnam’s Law on Bankruptcy and Rehabilitation No. 142/2025/QH15, passed by the National Assembly on December 11, 2025, does something many regional counterparts do not yet attempt: it instructs parties and arbitral tribunals on exactly what happens to an arbitration once a debtor becomes insolvent. Together with the Law on Commercial Arbitration No. 54/2010/QH12, the new law improves upon what used to be an uncertain area of practice, now providing an explicit, mandatory sequence of procedures. Suspension and Termination of Arbitration Proceedings Under article 40(2) of the law, once a Vietnamese court accepts a bankruptcy petition, any arbitration that concerns the debtor’s financial obligations must be temporarily suspended as soon as the tribunal receives the court’s notification. If the court subsequently issues a decision commencing bankruptcy proceedings, article 59(2) takes a further step: the suspended arbitration is terminated outright, and the underlying case file is transferred to the court handling the insolvency for resolution. The two provisions work as a sequence: first suspension, then termination and transfer, rather than as independent triggers. Meanwhile, article 60(4) reinforces this effect by vesting the bankruptcy court with exclusive jurisdiction over all claims against the debtor from the date the petition is accepted. Notably, this mechanism operates automatically, without the need for the insolvency court to issue a separate anti-arbitration order. The tribunal simply suspends or terminates the proceeding by operation of law once notified; however, Vietnamese law currently provides no procedure by which a party can apply to the insolvency court for permission to continue the arbitration despite the statutory effect. Practitioners with a Vietnamese counterparty in arbitration should treat notification of a bankruptcy filing as something to flag to the tribunal immediately since continuing to arbitrate a claim that has become subject to article 40(2) or 59(2) risks producing an award vulnerable
